GATE.

SPECIFICATION forming part of Letters Patent No. 438,050, dated October'7, 1890.

Application filed June 19, 1889. Renewed August 7, 1890. Serial No.361,356. (No model.)

To all whom it may concern.-

Be it known that I, WILL FRANCIS BENNETT, a citizen of the UnitedStates, and a resident of Logansport, in the county of Cass and State ofIndiana, have invented certain new and useful Improvements in Gates; andI do hereby clare that the following is a full, clear, and exactdescription of the invention, which will enable others skilled in theart to which it appertains to make and use the same.

My invention relates to improvements in that class of farm-gates orother gates that, in addition to being opened and closed by pedestrians,may be opened and closed by approaching and receding vehicles; and itconsists in the construction and novel combination of parts, as will behereinafter fully described and claimed.

Figure 1 of the drawings is a view in per spective of the improvedguiding-block to be used in connection with a gate that is designed tobe opened automatically. Fig. 2 is a view of a gate provided with theimproved block and the ordinary operating crank-rods and lever, by whichthe gate is swung to and fro on its hinges; and Fig. 3 is a detail viewof one of the operating-levers.

Referring by letter to the accompanying drawings, A designates thehinge-post, and C D the pintles in the hinge-post, upon which the gateis hung to swing open and shut.

E and F are double-crank rods, supported in suitable bearings so thatthey may be operated by the wheels of passing vehicles.

G and H are levers connected to the crankrods and-having catches I todetain the gate till the wagon has passed. The novelty in this instanceconsists in the guide-block M, secured to the hinge-post by a bolt andnut or in any other suitable manner. This guideblock comprises a headportion N, having two nearly V-shaped projections P Q, with theirforward enlarged ends separated by a vertical passage or groove R, thelower end of which communicates with the cam-shaped groove R, which isarranged at substantially a right angle to the projections and thevertical groove and is beneath the under face of the projections.

The gate is provided with a pin S, having a friction-roller T, which isadapted to travel in the head-block when the gate is opened and closed,as will presently appear.

This being the construction, the operation is as follows: When the gateis closed, the friction-roller T is immediately below and in line withthe vertical groove R of the headblock and the inner ends of the leversare under the hinge-post of the gate. When it is desired to open thegate, one of the levers is depressed at the outer end, which elevatesthe inner end, causing the same to lift the gate and move thefriction-roller up the groove R to clear the same,when it will traveldown the upper face of one of the projections, consequently opening thegate, and the catch I on the lever will, when the gate is opened, retainthe same. To close the gate, it is merely necessary to release thecatch, when the friction-roller will travel back in the groove R andassume its normal position, thus closing the gate, as will be readilyunderstood from the foregoing description and drawings.

Having thus fully described my invention, whatI claim as new, and desireto secure by Letters Patent, is-

1. In a gate, the combination, with the head-block having theprojections and the vertical and cam grooves, of the gate having the pincarrying the roller arranged in the cam-groove and under the verticalgroove,

and the levers having their inner ends arranged under the hinge-bar ofthe gate,whereby when said inner ends are elevated the gate is caused toopen, substantially as described.

2. In a gate, the combination of the pivot ed levers, the latchescarried by said levers, the gate having its hinge-bar above the innorend of the lovers, the pin carried by the gate, and the head-blockhaving the vertical and cam grooves arranged and adapted to servesubstantially as described.

3. The combination of the-gate carrying the pin, the head-block havingthe vertical groove and the cam-groove, the levers for elevating thegate, and the latches on the levers for retaining the gate,substantially as described.

In testimony that I claim the foregoing as my own I have hereuntoaffiXed my signature in presence of two witnesses.

.WILL FRANCIS BENNETT.
